From this point the straw, which is c now denuded of grain, will be delivered over the tail of the apparatus either to fall upon the ground, or to bereceived. or picked up by any supplemental devices for conveying it avvay' In `many required, under which conditions the cylinder and its shaft may be lifted out -of the journal boxes and the concave may be also removed; to facilitate this a portion of screen 5 is hinged as shown at 30. The two vibrators 5 and 7 may then be connected by a short, similarsection, so that the wholeof this vibrating conveyer will bein a line, andl the straw will be conveyed out and4 discharged without the intervention of the second threshing.- This second. threshing is particularly useful upon grain which 'may be damp and tough and not easily separated from the straw Vand husks.

The vibrators are operated by means of Vcams, and return springs. vA cam shaft'is.-

`tc throw the conveyer back with a jerk or snap, which being stopped abruptly, will' cause the materialupon the conveyer. to move toward the rear by a series of'continuo 'us short movementsV by which the straw 'gradually reaches the second threshingmechanism, or if it is absent, the` discharge end of the carrier. The .threshed grain headsfandY heavier chaff will fall through this conveyer, which is inthe form of open or separated transverse slats, andthe grain thus falling through. will be received upon This conveyer 1s grain and to deliver it'` into a receiving shoe 16.

In the space beneath the feeder v2 and the threshing cylinder 3 is located a centrifugal blast fan` 10 which may be driven by pulleys c upon. the threshing machine shaft and tl direction. yboard 11 serves to deflect the current of air fromthis fan so-that it kpasses beneath and through the` screen conveyer 4'., also through the slotted shakingl table 5, so as to drive out the lighter worthless chaff which is discharged toward the rear end In order to regulate the blast, I have .Y 'shown a number of deflectors 12 mounted and turnable upon horizontal shafts, so that `cases it willbe found` that the second threshing mechanism 6 willl notbe the angle of the deiiectors lmay be changed and 1 the discharge through the conveyer screen. regulated. "A regulating door 12ELU controls the amount of air discharged by the fan. In order to prevent the material from being thrown olf at one side or the other of the'conveyers, I have shown sloping sides i l convergingl toward the conveyer, whereby the grain and material is held toward the center and 'prevented fronifalling off :at the side edges. e

The shoe 9 will havereceived the grain and partially threshed` material which is still valuable from the upper carriers 5 and 7 and delivered .from the'iendy of the carrier L This shoe 9 is suspended and agitatedt in the usual manner for such shoes and prof i vided with. screen surfaces, and a'second fan y or blast apparatus 131s located :isothat it` discharges air beneaththe shfoe 9 to drive off any remaining chaff. The materialthat does not pass through the screens of the shoer9 will bedeliveredover the end of the shoe and a small'ithreshing mechanism 14 located Just beneath the-'discharge end iof the shoe, willreceive unthreshed heads and material falling over f theend lof this shoe` and completethe threshing. of these heads. The grain fallingthroughthe shoe and valso delivered from this last threshing mecha-1` nisin will be received upon a canvas convey-y Y ing belt or draper l5 which carries it back to the vicinity of the fancasing 13 and it! is dropped thence vupon the final shoe .16j

containingithe usual screen and sieves. final` fan 17 furnishes air, a blast ylof which is directed through Vthe lscreens 16 so as to discharge any `remaining,chaff or worthless material, and the grain which falls upon the e Y lower screens of the shoewill be delivered to a'wormcon'veyer 18 b v which it is delivered l at .the side of the :machine and may be de`Vl livered either directly linto sacks orreceive'rs,V Y Y or it may be delivered to elevators which,`

will raise it to a desired point of delivery.

The material Vwhich isdischarged at the end Vof shoe 16 will be received into a` trough'or oonveyerl) from which an elevator-conveys the material to shoe 9 and the threshing cylinder 14 whichis located at the mouth of theshoe 9.- Thismaterial that -is thus raised to the final threshing, may consist of brokenheads that may have been par'- tially threshed and separated from the straw i or grains, the husk of which is so tough-that I it has not been removed by the previous threshing, and this last threshing is designed to complete the cleaning of the grain to such r an extent that no supplemental grain cleaner such as is usuallyeinployed with threshing` machines will not be needed.v The endless conveyer =belt 20 eXtendshoi-izontally within the lower part of the machine and is -provided withinclined side ,guards 21 by `which any falling material will` be directed upon l`172,o 111 i Y v the belt. This belt vreceives both threshed or unthreshed heads which fall through the conveyeis above, and carries such niaterial backward and delivers it luponthe final vibrating shoe 16, journaled upon run-,v ners 27` and vibrated by mecha-nism as 'shown at 26, where the clean grain passes through the screens and is delivered tothe final screen conveyer 18, which is connected to screen 16. Any remaining unthreshed heads or material needing further treatment is delivered to the rear screen conveyer and elevated to the thresher 14, as previously described. :,s
